Three data enrichment tools worth picking in 2026, ranked by leverage. The category has been remade by AI columns and waterfall enrichment — the best tool now isn’t a database, it’s a substrate.
1. Clay — the data orchestration substrate
Clay is the spreadsheet-native enrichment + outbound orchestration platform. AI columns at scale (powered by Claude), routing across 100+ data providers, conditional logic, webhooks. Best-in-class. ooligo score: 9.2.
What it replaces: ZoomInfo + Hunter + Lusha + 20 niche providers + the Make/Zapier wiring between them.
Where to start: one list. Pick a target ICP, dump 1,000 companies into Clay, run enrichment + AI scoring, send the top 50 to Outreach or Salesloft. The math becomes obvious immediately.
ZoomInfo is still the deepest single B2B database for North American mid-market and enterprise. Pair it with Chorus (now bundled) for a coherent revenue platform. ooligo score: 8.0.
What it replaces: itself, mostly. The cleanest answer for “I need one data vendor” if you don’t want to wire Clay.
Where to start: if you’re already on ZoomInfo and outbound is working, don’t rip it out. Layer Clay on top for the AI-column work that ZoomInfo can’t do.
Apollo bundles enrichment + sequences + dialer at a price ZoomInfo can’t match. The right answer for SMB and early-stage teams that want one tool, not a stack. ooligo score: 8.3.
What it replaces: ZoomInfo + Outreach + a separate dialer at roughly 1/3 the cost.
Where to start: if you’re under 25 reps and outbound is a meaningful motion, default to Apollo. Graduate to Clay + Outreach when you cross 25 reps.
Cognism — strong in EMEA, less coverage in North America. Pick if you’re EMEA-first.
Lusha, Hunter, RocketReach — fine point-tools. Clay routes to them automatically — buy them through Clay, not direct.
LinkedIn Sales Navigator — table stakes; assume you have it. Not really an enrichment tool.
The minimum viable enrichment stack
If you’re picking new:
Building real outbound and want maximum leverage: Clay
Need one enterprise database, simple stack: ZoomInfo
SMB, want bundled sequences + data: Apollo
Most growing teams end up at Clay + (ZoomInfo or Apollo). Clay is the orchestrator; the database vendor is just one of many sources Clay reads from. Stop trying to make the database the center of the stack.
